PAPER-MAKING MACHINE.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed January 26, 1906. Serial No. 297,984-

, an apron and passed around heated cylinders for the purpose of drying the web; and my invention is especially adapted for use in such a machine in which the drying-cylinders are arranged in a single row.

The object of my invention is to provide a machine of the character last described with means for controlling the supply of heat to the cylinders so that the paper or web shall be uniformly and evenly dried as it passes about the cylinders and through the machine; and a further object of the invention is to utilize to a great extent the parts regularly forming a paper-making machine. A form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which Figure 1 isa view in side elevation of a portion of a paper-making machine, showing my improvement applied thereto. Fig. 2 is a detail view with parts broken away and looking 7 111 a direction endwise of the machine, showing the means .for attaching my improvement. Fig. 3 is a detail top or plan view of the regulator with pgarts broken away to show construction. ig. 4 is a detail view showing a modified form of the invention.

My present invention is for the purpose of enabl' g a regulator to be produced with the fewest number of parts and to utilize the regular web-rolls of the machine in carrying out my invention. The regulator itself, independent of this roll except in combination with other devices, forms no part of my pres ent invention. It forms the subject'matter of a pending application filed by me July 24, 1905, of Serial No. 271,117, and to which reference is hereby made. In devices of this class prior to the present invention and including the device of my pending ap lication above referred to, a separate roll as been employed for the purpose of operating the regulator, this roll, in fact, forming a portion of the regulator. This form of construction is not readily adapted for attachment to all forms of paper-making machines, and in an endeavor to adapt the regulator to different forms of machine I have demonstrated that the regular web-rolls forming a part of the paper-making machine may be employed in place of the additional'roll which has heretofore been supplied.

In the accompanying drawings I have illustrated a paper-making machine of peculiar construction in connection with which a device embodying my invention is used, and in mounted on legs or supports 1 and having a supporting-rail 2 extending lengthwise of the machine, the legs being disposed at suitable intervals along this rail. It will of course be understood that this frame includes 'a part located at each side of the machine, the drying-cylinders 3 being supported in suitable hearings on the frame. It will also be unclass. ,Arches 4 are mounted on the rail 2, an

arch being usually provided appurtenant to each drying-cylinder, and on these arches a top rail 5 is located, the frame being adapted for supporting the various web and apron supporting rolls to cause proper travel of the web of paper through the machine.

The exactmanner of mounting the web and apron supporting rolls, with the exception hereinafter named, has not been shown, for the reason that this is well known to those skilled in the art, the views being somewhat diagrammatic in this respect. The web and apron supporting rolls appurtenant to a pair of cylinders only has been shown herein, as this will be sufiicient for a complete and thorough understanding of the application of the invention.

The web of paper 6 is carried through the machine, this web being carried by the apron 7 and passing between said apron and the cylinder, by means of which it is dried. The apron 7 is carried about the cylinders, passing over apron-supporting rolls 8, located above the line of support of the several cylinders, the apron passing from one apronsupporting roll about the cylinder and upward to the next apron-supporting roll, then over a second apron-supporting roll, and then these drawings the machine includes a frame derstood that heat is applied to the cylinders in a manner Well known to machines of this 301 chi-I16, 'f;
